Small pigeon hole pockets are available along the wall on the bed-head side of the van. I'm going to install two with lights and 12V power sockets, and possibly three more above the kitchen table wall. The test box is installed in the smallest available spot, all remaining cavities are larger. You should be able to work out what's going on from the pictures.
I went looking for Pixel and found her through the window on the wrong side... She hasn't escaped for over a year. Usually it's a result of an exciting bird chase that ends up somewhere high. I moved the van-ramps to a new location after finding her attempting another escape 5mins later...
The 20mm x 1mm polycarb strips across the top of the fence have been flawless for keeping the cat in. The only failures have been opportunities to bypass them. (like the van ramps resting against the kayak enclosure that connects to the roof today)
The box is doweled in with twelve x3mm dowels...aka kebab sticks. I've yet to sand down and clean up the front face after doweling. It'll be cleaner afterwards...
